Dunlop spring rates

Does anyone know what the spring rate of the Dunlop FF 9092 tires is?

Seems to me tire spring rates are pretty high, like over 1000#/inch.

Thanks, are the rates the same for the front and rear tires?

I have built a rig to test tire rates but haven't done any Dunlops yet. I should be able to come up with some. May not be till the weekend though.

Has anyone figured this out for the dunlops?

depends on the size of the holes
